DC vs. AC magnetic waves

[ElectroMichel]

Is there any difference as to how a DC magnetic wave effect the relative permeability of an alloy, compared to an AC magnetic wave?

 

[EdStainless]

Yes

[ElectroMichel]

in which way?

 

[EdStainless]

It depends on the magnetic properties of the alloy, and the frequency and intensity of the field.
Start with any basic text on ferromagnetics.

[MagBen]

All else equal, DC relative permeability is always bigger than AC perm.

"DC magnetic wave effect"? In what sense?

 

[dgallup]

If it's steady state (DC) there is no wave, there is no transient. Thus resistivity is unimportant to the magnetic field. For AC and transient fields there will be resistivity and skin effects.
